Matthew Roloff, who stars with his wife and kids in the hit TLC reality show “Little People, Big World” was busted for driving under the influence of alcohol, according to published reports.

Roloff, a 4-foot, 2-inch dwarf, was allegedly swerving in a van on a road near the family home in Oregon’s rural Washington County.

He “allegedly failed the field sobriety test and was arrested,” according to a copy of the June police report obtained by “Entertainment Tonight.”

Roloff, 45, was also cited for refusing to take a breath test and for failing to drive in his lane, “ET,” reported.

He could be reached for comment.

Roloff’s show is in its third season. It chronicles the travails of Roloff and his wife, Amy, another dwarf, as they raise their four kids, two of whom are also dwarfs and two of whom are normal height.
